Parks:

As the National Park Service reshapes the way its parks are managed, a former NPS official weighs in on the potential changes. Don Castleberry, former NPS Midwest regional director, talks about the need to put resource protection above other competing priorities, such as the growing use of recreational vehicles in national parks. Castleberry, a member of the Coalition of National Park Service Retirees who oversaw both Grand Canyon and Everglades national parks, also addresses the agency's maintenance backlog and the increasing demands being placed on park managers.
